Perhaps but I've used both a Hololens and Google Glass, and the Hololens is light-years ahead. It is easily capable of the 'AR repair' application. Glass on the other hand was very 'meh'. The voice interface was horribly unreliable (think 2010-level speech recognition), and it is really just a convenient small display, not proper AR.

I tried a hololens in real life to measure the distance between bowling balls (English style bowls) and it worked really well superimposing an arrow between the balls with the distance.

For me it was more impressive than glass which when I tried it mainly had me wondering why the photos were so much fuzzier than you could take with you phone.
